IMPROVEMENT lN BOOK-BINDING.

Specification forming part of Letters Patent No. 211,616, dated January28, 1879; application filed November 15, 1878.

To all whom it may concern:

Be it known that I, EDWARD STANLEY BOYNTON, of Bridgeport, county ofFairfield, Connecticut, have invented certain Improvements inBook-Binding, of which the following is a specification:

This invention relates to the means of securing the leaves of eachsignature together, and the signatures themselves to each other and tothe transverse binding-cords and consists in the combination of partshereinafter described, by which these objects are most perfectlyaccomplished, and a reliable and properly elastic binding is secured.

In the accompanying drawings, Figure 1 is a perspective view of a bookconstructed according to my invention, no stiff covers being shown. Fig.2 is a plan thereof when opened in the fold of one of the signatures.Fig. 3 is a transverse section of the book at the line at a: of Fig. 1.Fig. 4 is a View of the back of a portion of the book, showing themanner of uniting the signatures, and also showing the position in whichthe ends of the longitudinal cords, hereinafter described, may properlybe secured.

A represents the body or leaves of the book. B B are cords or twines,one of which is located inside of and against the fold of eachsignature, extending the entire length of the page, and its ends (I (Ibeing drawn through the fold of the signature, so as to lie upon theback thereof. (J (J are the binding-cords which secure the signatures toeach other and the back of the book to the covers, the cords (J 0 beingsewed through the saw-cuts in the backof the book,and looped or turnedaround the cords B B, and tightly drawn up, so as to hold the latterfirmly in place and the signatures together.

The work of sewing in these cords B and (J may be performed either byhand or by machine. or partly by each, and the order and mode ofoperation may be, and probably will be, somewhat varied to accord withthe mean adopted for executing the work. I

When the work is done entirely by hand, the cords B B may be first laidin place on the inside of and against the fold of each signature, asshown in Fig. 2, and the cords (J (J sewed through the saw-cuts, andentirely around the cords B B, with a needle suitable for that purpose;but when the work is done either wholly or in part by machine, the cords(J (J may be partially sewed into a signature, so as to form loops forthe cord B, and the latter inserted in those loops, either by means of along needle adapted to the purpose and worked by hand, or by a shuttleoperated by machinery, the latter, of course, being the most expeditiousmode of doing the work.

A machine similar to thatdcscribed in the Letters Patent of the UnitedStates No.

203,530, granted to me May 14, 1878, with a proper shuttle for carryingthe cords B B through the loops of the cords O O and layin g them inplace, and appropriate mechanism to operate such shuttle in place of thepin supplying the feeding mechanism described in said patent, wouldfurnish an efficient mechanism for the rapid performance of the work.

In case the cords B B are sewed in one continuous cord extending throughthe entire book, such continuous cord must then be out at the end of thepages, so asto make the cord B for each signature a separate andindependent cord, having no connection at the end of the page with thecorresponding cord in the next signature. The cords (J (J having beensewed through the saw-cuts and around the cords B B, as described, Ithen, by pulling upon the two cords (J O which are nearest the ends ofthe book, draw the ends 01 d of the cords-B B through the saw-cuts, soas to bring them out upon the back of the book, as indicated in Fig. 4,and, discarding those cords (J (J by which the ends d d have been drawnthrough, I secure these ends 01 d firmly to the back of the book withglue, or by some other reliable mode of fastening, and preferably in theposition indicated in Fig. 4. The binding of the book is then completedin the usual manner, the ends of the remaining cords (J 0, being securedto the cover as ordinarily practiced.

This mode of binding secures great strength, permanence, andflexibility, effectually preventing the loosening of the leaves of thebook by handling. It also has the advantages over the mode of bindingdescribed in the Letters Patent of the United States No. 193,109,

granted to me July 17,1877, that the longitudinal cords B B, beingflexible, give a more binding-cords O O, the ends d d of the said I cordB B being drawn through the fold and secured at the back of the book,substantially as hereinbefore, set forth. 7
